Ko te waea utu he takirua waea me te paparanga ārai he rite te uara ingoa ki te kaha hikohiko wera o te takirua wera i roto i tētahi awhe pāmahana (0~100°C). Ngā hapa nā te huringa pāmahana i te hononga. Mā te ētita e whai ake nei e whakaatu ki a koe te rauemi o te waea utu wera, te mahi a te waea utu wera, me te whakarōpūtanga o te waea utu wera.
1. He aha te rauemi o te waea whakakapinga thermocouple?
Ko te waea utu whānui me rite ngā irahiko pai me ngā irahiko kino ki ngā rauemi pai me ngā irahiko kino o te thermocouple. Ko ngā thermocouple momo-K he nikara-kāmiuma (pai) me te nikara-hiriko (kino), nō reira, e ai ki te paerewa, me whiriwhiri ngā waea utu nikara-kāmiuma-nikara-hiriko.
2. He aha te mahi a te waea whakaea werawera?
Hei whakaroa i te hiko wera, arā, te pito makariri o te thermocouple pūkoro, ka hono atu ki te taputapu whakaatu hei hanga i tētahi pūnaha ine pāmahana. He rite tonu te whakamahi i te paerewa ā-motu o IEC 584-3 "Thermocouple Wāhanga 3 - Waea Whakautu". Ko te nuinga o ngā hua e whakamahia ana i roto i ngā momo taputapu ine pāmahana, ā, kua whānuitia te whakamahi i roto i te mana karihi, te hinu, te matū, te whakarewa, te mana hiko me ētahi atu tari.
3. Te whakarōpūtanga o ngā waea utu thermocouple
Ko te tikanga, ka wehea ki te momo toronga me te momo utu. Ko te hanganga matū ingoa o te waea koranu o te momo toronga he rite ki te mea o te takirua wera ōrite, nō reira he rite tonu te pūmanawa hiko wera. Ko te "X" te tohu i roto i te tauira, ā, ko te hanganga matū ingoa o te waea koranu o te momo utu he rite tonu. He rerekē i te takirua wera ōrite, engari i roto i tōna awhe pāmahana mahi, ko te pūmanawa hiko wera e tata ana ki te uara ingoa o te pūmanawa hiko wera o te takirua wera ōrite, e tohu ana i te "C" i roto i te tauira.
Ka wehea te tika o te utu ki te taumata noa me te taumata tika. Ko te hapa i muri i te utu o te taumata tika he haurua noa iho o te taumata noa, e whakamahia ana i ngā wāhi he nui ngā whakaritenga tika o te ine. Hei tauira, mō ngā waea utu o ngā tau tohu S me R, ko te manawanui o te taumata tika he ±2.5°C, ā, ko te manawanui o te taumata noa he ±5.0°C; mō ngā waea utu o ngā tau tohu K me N, ko te manawanui o te taumata tika he ±1.5°C, ko te manawanui o te taumata noa he ±2.5℃. I roto i te tauira, kāore te taumata noa i tohua, ā, ka tāpirihia te taumata tika ki te "S".
Mai i te pāmahana mahi, ka wehea ki te whakamahinga whānui me te whakamahinga ātete-wera. Ko te pāmahana mahi o te whakamahinga whānui ko te 0 ~ 100 °C (ko ētahi he 0 ~ 70 °C);
Hei tāpiritanga, ka taea te wehewehe i te matua waea ki ngā waea utu kotahi-aho me ngā waea maha-aho (waea ngohengohe), ā, ka taea te wehewehe ki ngā waea utu noa me ngā waea utu ārai i runga i te mea he paparanga ārai kei a rātou, ā, kei reira anō ngā waea utu mō ngā ara iahiko haumaru ā-roto e whakatapua ana mō ngā wā ātete-pahū.
